Description of problem:

RHEL 8 servers are showing they need an errata installed but the servers are up to date.  One errata, RHEA-2020:4724 in particular, was only showing up after installing this package:

  perl-Mozilla-CA-20160104-7.module+el8.3.0+6498+9eecfe51.noarch


2 servers show needing this errata from the portal, however, only one shows as having available via yum.  But neither will update that errata:

First server (RHEL 8.3) with candlepin id 0fb44c85-4669-4b36-82e3-45a138a03719:

[root@rhel8-antso-dev ~]# yum list-sec | grep "4724"
RHEA-2020:4724 enhancement    perl-Mozilla-CA-20160104-7.module+el8.3.0+6498+31ea7642.noarch

Second server (RHEL 8.2) with candlepin id  64104b1e-7b07-4465-b494-48bed39eb1d8 :

[root@dhcp-12-212-238 ~]# yum list-sec | grep 4724

Yet both show needing the errata from Customer Portal.

I tested this on a fully up to date RHEL 8.3 server (decommissioned now), but the only way to clear the errata, was to remove the perl-Mozilla-CA package.  If that package was installed, then only one errata was displayed in customer portal, RHEA-2020:4724.

Version-Release number of selected component (if applicable):
RHEL 8 (8.2 and 8.3)

How reproducible:
always

Steps to Reproduce:
1. Register a rhel8 system to the portal
2. If perl-Mozilla-CA package is not installed, install it
3. Customer portal shows RHEA-2020:4724 as needing to be installed but can't install it

Actual results:


Expected results:


Additional info:
The errata title is this:
~~~
An update for the perl-IO-Socket-SSL:2.066 and perl-libwww-perl:6.34 modules is now available for Red Hat Enterprise Linux 8.
~~~
- I also tried installing perl-IO-Socket-SSL and perl-libwww-perl but that didn't help.
- I noticed there are 3 versions of the perl-Mozilla-CA package in that errata, all with different context values (the trailing hex-dec before the .noarch).  The package I have installed has context 9eecfe51.  Not sure what context is, but may have an impact.
